I have a Dell XPS L501X with exactly the same problem. The fix above: > volume control -> configuration to Analog Stereo Duplex (unplugged)
I the only thing that has worked for me. I've tried multiple other suggestions on other sites, include renaming .config/pulse folder then reboot, force-reload of alsa, removing the pulse-audio and alsa-base packages from the system, and reinstalling them, and reviewing all settings in alsa mixer. Ubuntu works perfectly on this laptop. I had 19.04 previously, and sound worked fine. An upgrade to 20.04 didn't work as selecting the nVidia video driver nvidia-driver-390 would not let the OS boot into the GUI. What is strange is a complete wipe and reinstall of 20.04 from scratch worked fine, and that video driver was selected automatically. I'm so glad I found this post, as I now have sound again. For now I'm content changing the setting by hand after a reboot. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876046 Title: [XPS L501X, Realtek ALC665, Speaker, Internal] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1876046/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
